When documentation needs to be built from project materials and kept useful as those materials change, AI documentation generators offer different workflows. Compare source types and API spec support to see what each can use, then look at code repository sync and automatic updates if you need documentation to track revisions. Output formats and hosting model help clarify how you can deliver and maintain the result. Mintlify, Scribe and Tango are among the entries, alongside AutomaDocs and Documentation.AI. Free plan availability and Paid from provide cost context as you weigh what fits your sources, workflow and preferred way to share documentation.
